1926, New York City. It's the roaring twenties but not as history remembers it. Coal-powered cars line the streets, while zeppelins and biplanes patrol the skies. The US is locked in a bitter cold war with a British Empire that still covers half the globe and the “Lost Generation” is drinking away the nightmares of the trenches. In Manhattan a run-down police force is losing the fight against a tide of powerful mobsters, and against one in particular: The Roman. His henchmen – not all of them human – stalk the streets, and the body count is rising. It's a time in need of a hero. It's a time in need of The Ghost.
